CHAPEL HILL — While considering the bothersome slide his North Carolina team is trying to reverse against Virginia, coach Mack Brown recalled a message this week from his time at the helm of Texas.

The Longhorns had lost four straight games to rival Oklahoma, some by blowout margins, and Brown sought the advice of Darrell Royal, the college football legend and all-time winningest coach in Texas program history. Royal was in his 80s then.
